Effects of short-term brachial arterial vasodilator infusions on forearm blood flow response to acetylcholine

Because short-term administration of both nitro-prusside and isoproterenol caused a similar augmentation of the FBF response to ACH, we believe that a transient increase in shear stress alone may “condition” the endothelium and improve its response to endothelium-dependent vasodilator stimuli.
